Partisan composition of state legislatures
|
The partisan composition of state legislatures refers to which political party holds the majority of seats in each state Senate and state House. Altogether, there are 1,973 state senators and 5,413 state representatives.
Sixty-one state legislative chambers around the country have an even number of members, raising the possibility of a tie between the two major parties. In some instances, a bipartisan coalition of legislators is formed to act as leadership.[1] This tactic has not been the universal approach, however; some legislative bodies have used a coin toss, gubernatorial choice, shared time, choosing co-leaders, or dividing chairperson positions between the parties.[2]
A state government trifecta is a term to describe single party government, when one political party holds the position of governor and majorities in both of the state's legislative chambers.
As of September 2, 2024, there are 23 Republican trifectas, 17 Democratic trifectas, and 10 divided governments where neither party holds trifecta control.
Cumulative numbers
As of September 2nd, 2024, Republicans controlled 54.86% of all state legislative seats nationally, while Democrats held 44.25%. Republicans held a majority in 56 chambers, and Democrats held the majority in 41 chambers. Two chambers (Alaska House and Alaska Senate) were organized under multipartisan, power-sharing coalitions.

Changes in the number of seats
2022
- See also: Redistricting
As a result of redistricting conducted after the 2020 census, the number of state legislative seats in the country changed. Wyoming's new state legislative maps created one new Senate seat and two new House seats, resulting in 31 state Senators and 62 state Representatives. This increased the number nationally to 7,386 legislators—1,973 state senators and 5,413 state representatives.
It is relatively uncommon for states to change their numbers of legislators during redistricting. New York increased its number of state Senators by one after both the 2010 and 2000 censuses. After the 2000 census, two states—North Dakota and Rhode Island—reduced their number of legislators in both chambers.
